Create new file in Blender 2.79
That is normal behavior. Blender uses a template file, and to create a new document is to reload the template file. From the manual: &quot;New (Ctrl-N): Clears the current scene and loads startup.blend.&quot;
Blender 2.79 is not the most recent release, and more recent releases of Blender have changed the phrasing of this menu option and it now gives a choice of templates.
The latest 2.9 release is available here: https://www.blender.org/download/
And the Long Term Support release of 2.83 is here: https://www.blender.org/download/lts/
